Write equations to represent the following observations.
(a) A mixture of Mg(OH)2(s) and Zn(OH)2(s) is treated with NH3(aq). The Zn(OH)2 dissolves, but the Mg(OH)2(s) is left behind.
(b) When NaOH(aq) is added to CuSO4(aq), a pale blue precipitate forms. If NH3(aq) is added, the precipitate redissolves, producing a solution with an intense deep blue color. If this deep blue solution is made acidic with HNO3(aq), the color is converted back to pale blue.
